A shaft 104 is formed inside the support wall 103 of the right half 100b, and the shaft 104 is formed inside the support wall 103 of the right half 100b.
Of the left half 100 is inserted into the shaft 104 through the shaft insertion hole 106 of the lever 102.
a and the right half 100b,
The lever 102 is rotatably supported on the frame body 100 by rotation.

[0003]

In the conventional fastener, the frame 100 is divided into a left half 100a and a right half 100b in order to pivotally support the lever 102 to the frame 100. In this case, the manufacturing cost is high, and assembly work such as screwing is troublesome and troublesome. The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a pachinko machine capable of pivotally supporting a lever of the above-described fastener by one-touch operation. A fastener for fixing a game board.

[0004]

In order to achieve the above-mentioned object, a fastener for fixing a game board of a pachinko machine according to the present invention is provided with a frame body and a space in which a lever is located between support walls on both sides. A horizontal axis is integrally provided between the support walls on both sides thereof, and a cross-sectional C-shape having a fitting opening in which the shaft insertion hole of the lever is slightly smaller than the diameter of the horizontal axis of the frame body. The lever is inserted into the horizontal axis by pushing the insertion opening of the lever into the horizontal axis, and the shaft insertion hole is inserted into the horizontal axis to rotatably support the lever.

[0005]

In order to pivot the lever on the frame, the fitting opening at the end of the lever is pushed against the horizontal axis of the frame. As a result, the fitting opening is expanded by elastic force, and in this state, by pushing the lever, the insertion hole is fitted to the horizontal shaft and is rotatably supported.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a fastener for fixing a game board according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view thereof. In the figure,
Reference numeral 1 denotes a fastening tool, which is generally constituted by a frame 10 made of synthetic resin and a lever 20. The frame body 10 has left and right support walls 11, and mounting portions 13, 13 having screw insertion holes 12, 12 are integrally formed at front and rear positions between the two support walls 11, 11, and are formed in the center. Is formed with a space portion 14 opening vertically. The space 1
A horizontal shaft 15 for pivotally supporting the lever 20 is integrally formed between the two support walls 11 and 11 where the 4 is formed.

On the other hand, the lever 20 has a mountain-shaped projection 21 at the tip end thereof, and a metal spring rod 22 is provided on the top of the projection 21. Also, the protrusion 2
A shaft insertion hole 23 that fits into the horizontal shaft 15 of the frame body 10 is formed at the front end of the frame 1. The spring rod 22 is formed by bending a resilient wire-like member so as to have a substantially U-shape when viewed from a plane. Be worn. And, the shaft insertion hole 23
Is formed in a C-shaped cross section by providing a fitting opening 24 slightly smaller than the diameter of the horizontal axis 15 as shown in the figure.

The fastener 1 of the illustrated example according to the present invention is assembled in the following manner. First, the fitting opening 24 formed in the shaft insertion hole 23 of the lever 20 is abutted on the horizontal shaft 15 of the frame 10. Next, when the lever 20 is pressed strongly, the fitting opening 24 is expanded by the elastic force, whereby the shaft insertion hole 23 is fitted into the horizontal shaft 15 and the lever 20 is moved to the frame 1.
It is pivotally supported at 0.

FIG. 3 shows the fastener 1 of the present embodiment described above.
FIG. 4 is an exploded perspective view of a main part for explaining a configuration related to a fixture, and FIG. 5 is a cross-sectional view showing a fixed state of a game board. In the figure, reference numeral 30 denotes a pachinko machine, and the pachinko machine 30 has a front frame 32 mounted on a front surface of a side frame 31 so as to be freely opened and closed. A game board 34 is removably mounted on the back of the front frame 32 via a game board mounting frame 33. On the back of the game board 34, a prize ball collecting unit 35, a prize ball tank 36, and a prize ball payout mechanism are provided. A mechanism plate 38 to which back parts such as 37 are attached is mounted so as to be freely opened and closed.

Then, the above-described fastener 1 according to the present invention is fixed to the right and left sides of the rear surface of the mechanism plate 38 by screws 39. A through hole 40 is formed in the mechanism plate 38 so as to correspond to the space 14 of the frame 10, and a projecting piece 41 facing the space 14 of the frame 10 from the through hole 40 in the game board mounting frame 33.
Is fixed by a screw 43. The protruding piece 41 of the fixing tool 42 has a horizontal rod portion 22a of the spring rod 22.
Is formed with an engagement groove 44 with which the.

Therefore, to fix the game board 34, the mechanism plate 38 is brought into close contact with the back surface of the game board 34 by rotating the lever 20 to a substantially central position shown by a chain line in FIG. When the lever 20 is rotated to the position indicated by the solid line in FIG. 5 with the projecting piece 41 of the fixing tool 42 protruding into the U-shaped space of the spring rod 22, the horizontal rod portion 22a of the spring rod 22 The mechanism plate 38 is strongly pressed against the back surface of the game board 34 due to the reaction at the same time as the protruding piece 41 is drawn into engagement with the engagement groove 44, so that the game board 34 can be firmly fixed. it can.

[0012]

As described above, according to the fastener for fixing the game board of the pachinko machine of the present invention, the lever that pivotally supports the lever is positioned between the support walls on both sides. A space is provided and integrally formed, and a horizontal axis is integrally provided between the two support walls. On the other hand, a shaft insertion hole of a lever to be inserted into the horizontal axis is slightly smaller than a diameter of the horizontal axis of the frame body. It is formed in a C-shaped cross section having a fitted insertion opening, and the shaft insertion hole is fitted to the horizontal shaft by a one-touch operation of merely pushing the fitting opening against the horizontal axis and strongly pushing the lever to rotatably support the lever. In this way, the assembling work of the fastener is remarkably simplified, and there is no need to form the frame body in two parts as in the prior art and to fix the screws, thereby reducing the manufacturing cost. There is an advantage that the economic effect can be enhanced.
